type t struct {

}

func (this *t)HandleMessage(message *nsq.Message) error{
    fmt.Println(string(message.Body))
    return nil
}
func init()  {

    producer,_ = nsq.NewProducer("127.0.0.1:4150",nsq.NewConfig()) // 初始化生产者
    consumer,_ = nsq.NewConsumer("fwd","ch1",nsq.NewConfig())
    consumer.AddHandler(new(t))
    consumer.ConnectToNSQD("127.0.0.1:4150")
}
func main() {


    go func() {

    }()
    for{
        time.Sleep(time.Second)
        producer.Publish("fwd",[]byte("哈哈哈哈哈"))
    }

}

输出:
